China Sourcing Return & Defect Policy: How to Handle Bad Quality

Defect Types & AQL Acceptance Levels

AQL (Acceptable Quality Limit) is the maximum defect rate you are willing to accept. AQL 2.5 means you accept up to 2.5% major defects in the sample. For Japan-bound orders, tighten to AQL 0.65–1.0. Specify your AQL in the contract before production. For the full QC framework, see China quality control inspection.

Defect Remedy Options

Rework at the factory is the default remedy for most defects — it is fast, cheap, and the factory usually pays. Return & refund is rarely worthwhile: shipping a $3 product back to China costs $5–$15/kg in freight, so you lose money even if the refund comes through. Reserve returns for critical safety defects or high-value goods (electronics, jewelry) where the product value exceeds the return freight.

The 5-Step Defect Response Process

1. Document with photos & video — photograph every defective unit with a scale reference and annotation; shoot a short video of functional failures. This is your evidence. Pair it with a signed AQL defect sheet if an inspector was on site.
2. Notify the supplier within 3–7 days — send an email (not chat) with the evidence attached and a clear description of the defect type and quantity. Waiting longer weakens your claim.
3. Negotiate the remedy — propose rework, replacement, or discount based on the defect class. Be specific: "8% of units have a major leak defect; please rework the batch at your cost within 7 days."
4. Get a written agreement — confirm the remedy, timeline, and who pays in writing. A WeChat/WhatsApp screenshot is not enough; email is the standard.
5. Withhold final payment if unresolved — if you have not yet paid the 50% balance, hold it until the remedy is complete. If you have already paid, your leverage is reduced — which is why pre-shipment inspection is critical.

Contract Clauses That Protect You

The best defect policy is the one written into the contract before production. Include these clauses:

• AQL specification — "Major defects AQL 2.5, minor defects AQL 4.0, critical defects AQL 0."
• Pre-shipment inspection clause — "Buyer may conduct a pre-shipment AQL inspection. If the batch fails, the factory reworks at no cost and re-inspects before shipment."
• Defect-rate tolerance — "Major defect rate above 2% triggers mandatory rework; above 5% triggers full batch replacement."
• Warranty period — "Factory warrants goods against defects for 90–365 days from delivery; defects during warranty are reworked or replaced at factory cost."
• Payment tied to QC — "Balance payment (50%) is released only after buyer approves the pre-shipment inspection report."

Worked Example: 8% Major Defects → Free Rework + 5% Discount

A UK retailer ordered 3,000 LED desk lamps from a Shenzhen factory at $4.50/pc ($13,500 total). Yeatru's pre-shipment inspection found 8% major defects — the USB charging port was loose on 24 of 32 sampled units (extrapolated to ~240 units).

• Evidence: 40 annotated defect photos + a 3-minute functional test video (port falls out when cable is tugged). See how to build this evidence.
• Notification: buyer emailed the factory the same day the report landed, with photos and the AQL calculation.
• Negotiation: factory initially claimed "within tolerance." Buyer referenced the contract's AQL 2.5 clause and the 8% finding. Factory agreed to free rework of the entire batch (re-soldering the USB port) plus a 5% discount ($675) for the delay.
• Re-inspection: after 6 days of rework, a second PSL showed 1.8% major defects — within AQL 2.5. Balance released, shipment proceeded.

Outcome: the buyer received a compliant batch and saved $675. Without the inspection and photo evidence, the buyer would have paid the balance, received 240 broken lamps, and faced £3,000+ in UK customer returns.

Preventing Defects Before They Happen

• Clear spec sheet + golden sample — define materials, dimensions, tolerances, and finish in writing, and approve a pre-production sample as the golden reference.
• In-process QC (IPQC) — inspect during production (when 10–20% is complete) to catch defects early, before the whole run is wasted.
• Pre-shipment inspection before balance — never pay the 50% balance until an AQL inspection passes. This is the single most effective defect-prevention step.
• Contract defect clauses — AQL level, free rework on PSL failure, defect-rate tolerance, and warranty period.
• Long-term supplier relationships — factories that value your repeat business are far less likely to cut corners on materials.

How Yeatru Handles Defect Resolution

Yeatru manages the full defect lifecycle:

• Pre-shipment AQL 2.5 inspection with photo/video before your balance is paid.
• On-site rework supervision — we stay at the factory during rework to confirm it is done correctly.
• Re-inspection after rework at no extra charge.
• Contract review — we include AQL, rework, and warranty clauses in every purchase agreement.

Start with our pre-shipment inspection to catch defects before they reach you.

Frequently Asked Questions

1. What should I do if I receive defective goods from China?

Document every defect with photos and video, notify the supplier in writing within 3–7 days, and negotiate a remedy (rework, replacement, discount, or return). Withhold the final balance payment until the issue is resolved in writing. Never ship defective goods back to China without a written agreement — return freight is usually more expensive than the product value.

2. What is the difference between critical, major, and minor defects?

Critical defects are safety hazards or regulatory failures (e.g., exposed wiring, lead paint) — the entire batch must be rejected or reworked. Major defects make the product fail its function (AQL 2.5). Minor defects are cosmetic issues that do not affect function (AQL 4.0). The defect class determines the remedy.

3. Should I rework, replace, or get a discount for defective goods?

Rework at the factory is usually the best option for minor and major defects — it is fast and the factory often pays. Replacement is better when the defect cannot be fixed (e.g., wrong material). A discount or credit (5–20% off) is appropriate when you can accept the defect. Return and refund is rare and only worth it for critical defects or high-value goods, because return shipping to China is expensive.

4. What AQL level should I use for defects?

Most consumer goods use AQL 2.5 for major defects and AQL 4.0 for minor defects. Critical defects are always AQL 0 (zero tolerance). Japan-bound orders often use tighter levels (AQL 0.65–1.0). Specify the AQL level in your contract before production starts.

5. How long do I have to report defects to a Chinese supplier?

Notify the supplier within 3–7 days of receiving the goods or of the pre-shipment inspection. Waiting longer weakens your claim. The contract should specify a warranty period (typically 90–365 days) during which the supplier remains liable for defects found after delivery.

6. How do I prevent defects when sourcing from China?

Prevent defects by: (1) writing a clear spec sheet and approving a golden sample before production, (2) running in-process QC (IPQC) during production, (3) doing a pre-shipment AQL inspection before paying the balance, and (4) including defect clauses in the contract (AQL level, free rework if PSL fails, defect-rate tolerance, warranty period).

Common Pitfalls to Avoid

• Skipping pre-shipment inspection. Once the container is sealed and at sea, defects cannot be returned to the factory. A $150 AQL 2.5 inspection catches $1,000+ in defects before they cross the Pacific.
• Using the wrong AQL level. AQL 2.5/4.0 is standard for consumer goods; 0.65 for medical/safety products, 4.0 for low-value commodities. The wrong level either over-inspects (wasting money) or under-inspects (missing defects).
• Inspecting at the factory without photo/video evidence. A verbal 'pass' report is worthless when you receive 200 broken units. Demand dated photos of every defect category and a sealed sample retained at the factory.
• No defect rework timeline in the contract. Specify that defects must be reworked within 3–5 days at the factory's cost, with a re-inspection before shipment. Without this, factories delay rework indefinitely.
• Confusing 'passed QC' with 'guaranteed quality'. AQL sampling statistically estimates defect rate — it does not guarantee zero defects. Budget 1–3% for post-shipment defects and include a defect-credit clause in the contract.

Conclusion

Defective goods are inevitable in China sourcing, but a clear defect policy turns them from a disaster into a manageable cost. Classify defects (critical/major/minor), choose the right remedy (rework first, return last), document everything with photos and video, and back it all up with contract clauses — AQL level, free rework on PSL failure, defect-rate tolerance, and a 90–365 day warranty. The LED-lamp example shows how an 8% major-defect finding was resolved with free rework and a 5% discount, thanks to photo evidence and a pre-shipment inspection clause. The cheapest defect is the one caught before you pay the balance. Ask Yeatru about defect-protected sourcing — we include AQL, rework, and warranty clauses in every contract.
